No. 42,593 14 Claims. (CL 101--287)The present invention relates to a printing press and more particularlyto a portable printing press capable of being readily carried andtransported.

It is an object of the present invention to provide a printing presswhich is of a unique construction and which is provided with simple yeteffective operating means whereby quality printing is achieved.

v Another object of the invention is to provide a compact, lightweight,readily portable printing press which is always ready for printingwithout requiring further operations.

These objects are accomplished by providing the press with a base forsupporting the type and having a pivotal frame mounted on the base andcarrying a platen to receive the paper or the like to be printed andmove the platen into printing relation with the type with asingledirection, one-hand operation. The press has means for accuratelylocating the paper or material to be printed in juxtaposed parallelrelation with the type and guiding the paper into printing relation withthe type under the pressure of a novel toggle means during the printingoperation.

A feature of the invention resides in a novel handle construction whichfunctions to move the frame about its pivot from an open to a superposedrelation with the type and which thereafter moves the toggle units froma retracted position to a position in which they cooperate with means onthe base for pressing the platen against the type to effect the printingand which handle may be locked in the latter position and also serve asa carrying handle for the press when the press is a portable press madeof lightweight material.

A feature of the invention resides in the provision of means whereby thepressure of the platen against the type can be readily adjusted.

Another feature of the invention resides in the means forming a typeguard whereby the movement of the frame toward the base is limited,thereby preventing undue pressure of the platen against the type todamage the type.

Other features and advantages of the invention will be apparent from thespecification and claims when considered in connection with theaccompanying drawings in which:

FIGURE 1 shows the press in an open position.

FIG. 2 shows the press with the frame being moved to stop position.

FIG. 3 shows the frame in printing position.

FIG. 4 is a fragmentary sectional view of the locating means.

:FIG. 5 is a sectional view taken along line 5-5 of FIG. 3.

FIG. 6 is a top view of the portable press in closed relation.

As shown in the drawings, the press of the present invention comprises abase 10 having side walls 11 terminating in inturned flanges 12. Thecentral portion of the base provides a smooth level chase-supportingsurface 13 for supporting a chase 14 adapted to have type 15 heldtherein. The type can be individual type units, linoty-pe or can be woodblocks or the like plates which may be conveniently locked in the chasein the usual manner (not shown) and all are included in the term type asused herein.

As shown in the drawings, the chase is releasably locked to the base byhaving clips 15a adjustably secured to the back of the base by screws16, with the upper end 15a of the clip overlying the edge of the chaseas shown in FIG. 1. The front end of the chase is secured with a camlock or latch 17 having a tongue 18 engaging the chase when the latch ismoved into latched position.

The bottom of the base is provided with a plurality of bosses or bridgemembers 19 in each of which a supporting bushing or fixed stop 20 havinga conical recess 20a is inserted for locating the platen as will beexplained.

The base has pivotally mounted thereon a platencarrying frame 22. In theillustrated form of the invention the side Walls 11 are provided at theupper rear portions thereof with a bearing block 23 having a bearing orpivot pin 24 fixed therein and projecting inwardly of the side walls andadapted to pivotally mount the platen-carrying frame for movement froman open position, as shown in FIG. 1, to a closed printing position asshown in FIG. 3.

As shown in the drawings, the frame has a center portion provided with asmooth undersurface 25 forming a platen for cooperating with the typeduring the printing operation. The platen has disposed thereon acompressible inner member 26 having a tympan or draw sheet 27 extendingthereover and held in place by having the edges thereof folded aroundthe edge of the platen and held in place by pivoted bail locks 28, 29 atthe front and back of the platen. If desired, the back edge of theplaten is provided with clips or fingers 30 for locating a sheet ofpaper or other material 31 to be printed in position on the platen.

The frame has side flanges 32 which close the space between the platenand the side walls of the base. While the flanges may be made integral,they are herein shown as separate members secured to the platen byscrews 3-3. Secured to the side flanges at the back thereof are pivotplates 34 for the frame which are provided with elongate apertures 34afor receiving the pivot pins 24. The elongae apertures permit verticalmovement of the frame on the base during the printing operation. Aspring 35 mounted on the plate and bearing on the pivot pin normallytends to urge the frame and platen in a direction away from the base.

The material 31 to be printed can be held on the platen in various ways.In the herein illustrated form of the invention it comprises atransverse bar 36 having a pair of material-engaging fingers 37adjustably mounted thereon by wing bolts 37a to extend across theplaten. The ends of the bar are bent at right angles thereto to formmounting portions 38 pivotally connected by pivot 39 to the pivot plates34. A spring 40 is disposed around the pivot pin 39 and has one end 40adisposed under a lanced-out finger 41 on the pivot plate and the otherend 40b located under a lug 42 projecting lateraly from the mountingportion and tends to move the fingers into clamping relation with theplaten to hold the material thereto.

As the frame and platen are moved to open position, the lug 42 engagesunder the flange 12 and stops movement of the mounting portion andfingers. The frame, however, continues until finger 41 engages the endmounting portion 38 and is stopped in open position and from furtherrearward pivotal movement. It will be noted that this sequence ofoperation automatically positions the fingers 37 in the position shownin FIG. 1 to readily permit insertion of the material 31 when the frameis moved to open position. After the material has been positioned on theplaten, the platen is moved forwardly toward printing position and firstengages the fingers and thereafter the spring holds the fingers inclamping relation, thus effectively holding the paper or other materialin contact with the platen.

In accordance with the present invention novel means are provided forlocating and guiding the platen just prior to and during the printingoperation. This means comprises depending brackets 43 secured to thesides of the frame adjacent the corners of the platen by screws 44. Thelower ends of the brackets are provided with a lat eral flange or foot45. Each of the flanges has a sleeve 46 threaded therein provided with aplunger 47 having a pin 48 projecting through a bore in the lower endWall of the sleeve and urged into projected position by a spring 49. Aplug 50 threaded into the other end of the leeve provides for adjustmentof the spring pressure. As shown in FIGS. 2 to 4, the sleeves arealigned with bushing 2% on the base with the plunger pin being seated inthe conical recess a to accurately stop and locate the platen insuperposed, parallel, spaced relation with the type. While separatemeans may be provided for guiding the platen during the printingoperation to prevent slurring, in the illustrated form of the invention,the cooperation of pin 48 with the conical recess 29a serves thispurpose.

Novel means are provided for moving the platen from stopped position andpressing the material thereon into engagement with the type during theprinting operation. This means comprises a plurality of toggle units 51connected to the frame and cooperating with means on the base to effectthe required movement and pressure of the platen. Preferably, the toggleunits are disposed at predetermined locations about the platen toproduce uniform pressure of the platen against the type. Each toggleunit, as shown in FIG. 1, comprises a lower link 52 and an upper link 53having their adjacent ends pivoted together at 51a and connected to aconnector 54 on each side of the platen. The lower end of the link 52 ispivoted to the foot 45 of the bracket 43 while the upper end of the link53 projects upwardly in position to cooperate with an anvil 55 carriedby the flange 12 on the side wall of the base. A spring 56 mounted onthe bracket has its end positioned in a notch 57 in the end of link 53,as shown in FIG. 5, to tend to rotate the link and cause a stop pin 58to engage a stop lug 60 on the lower link to maintain the unit with anobtuse angle formed between the two links as shown in FIG. 1. In orderto operate the toggle units, a handle 61 is provided in the form of atransversely extending bail 62 forming a handgrip having legs 63extending through slots S in the flanges 32 and pivotally mountedintermediate their ends by shear pins 63a to one end of links 64 whichare pivotally connected at their other ends 64a to the forward end ofthe frame. The ends 6312 of the legs 63 are pivotally connected to theconnectors 54 on each side of the frame which interconnect the toggleunits to operate the toggle units. As shown, the legs are so shaped andarranged that the bail in itself forms a toggle actuator for theconnectors.

The handle not only serves as an actuator for the toggle units but isthe means for moving the frame to and from open position and is soconnected to the toggle units as to normally maintain the toggle unitsin a retracted position shown in FIG. 1. As the frame is moved by thehandle about its pivot into the stopping position in which the platen islocated adjacent, but in spaced superposed relation with the type, theretracted toggle links move through openings 12b formed in the flanges12 of the side walls as shown in FIGS. 2 and 6. When the frame reachesthis stop position, the handle is in the full line position, as shown inFIG. 2, and the toggle units are in the full line position. Continuedpressure on the handle will cause the handle to move relative to theframe about its pivotal mounting and cause the connectors 54 to move thetoggle units from full line position to the dotted line position of FIG.2 in which position the ends of the upper links engage abutments 65carried by the underside of the flange 12 adjacent the anvils 55 andlocate the upper end of link 53 in position under the anvil. Continuedmovement of the handle to the position of FIG. 3 will cause theconnector 54 for the toggle unit to move to the left and, because theabutment prevents movement of the upper end of link 53, it will move thepivot to the left and cause the toggle links to straighten out with theend of link 53 engaging the anvil and apply a downward pressure to theplaten. This will move the platen against the action of thespring-pressed plunger 47 and into engagement with the type to printtherefrom. The vertical movement of the platen with respect to the pivotpin during the printing operation is permitted by the yielding of spring35 on the pivot plate.

Preferably, the anvils are threaded into position, as shown in FIG. 1,and can be adjusted with respect to the base to control the pressure andmovement of the platen during the printing operation.

If desired, the toggle links can move through a straight angle to anobtuse angle in the other direction, as shown in FIG. 3, before a stop66 on the base engages the link 64 carrying the handle to stop it inthis position. When the handle is moved to this position, it will causethe platen to move downwardly with respect to the type and, as thetoggle links pass through the straight angle they will apply a maximumprinting pressure momentarily to the platen and press it against thetype and instantaneously thereafter relieve the maximum pressure as thelinks move to the other obtuse angular relation.

It will be noted in FIG. 4 that the end of the sleeve will engage thebushing and form a protective stop limiting the downward movement of theframe and preventing the platen from crushing the type during thisoperation and the sleeve can be adjusted with respect to the foot toaccommodate type of different heights.

In operation the handle is gripped in the position of FIG. 3 and movedupwardly relative to the frame to the position of full lines in FIG. 2,at which time the handle engages the end of the slot S in the upperframe. During the movement to this position the handle will cause theconnector 54 to move the toggle units into their normally retractedposition. Continued movement of the handle thereafter causes the upperframe to pivot about the pivot pin 24 to the open position shown inFIG. 1. As it moves to the open position of FIG. 1, the lug 42 on thepaper-holding fingers will first engage under the flange 12 andthereafter the finger 41 on the pivot plate will engage the end of themounting means 38 for the paper-holding fingers and stop the movement ofthe frame about the pivot. It will be noted that in the open positionthe entire frame is moved from over and spaced above the type so thatthe type can be inked with any suitable inking mechanism (not shown).With the platen in its raised position a sheet of paper 31 or othermaterial to be printed is inserted into position in which it engages theclips 30 at the edge of the platen to locate it in position. The handleis grasped and the frame is moved toward closed position. Initialmovement of the frame causes the spring to move the paper-engagingfingers into contact with the paper on the platen to hold it in positionthereon. Continued movement of the handle moves the frame to the fullline position of FIG. 2 in which the resiliently mounted stops carriedby the frame engage the bushings carried by the base and locate theplaten and the paper carried thereby in parallel, closely spaced,superposed relation with respect to the type. Continued movement of thehandle causes the connector 54 to move the toggle units from retractedposition into a position in which they engage the abutment 65 and locatethe toggle links under the anvils 55 carried by the base. This occurswhen the handle is in the dotted position of FIG. 2. Continued downwardmovement of the handle to the position shown in FIG. 3 causes the toggleunits to straighten and engage the anvil and apply pressure to overcomethe resilient locating means on the frame and move the material on theplaten into printing relation with the type and thereafter move thetoggle links beyond the straight position to the position of FIG. 3wherein the printing pressure has been released. This completes theprinting cycle after which the cycle is repeated and the frame moved toopen position and the sequence carried out again.

With this construction it will be seen that a single continuous movementof the handle in one direction operates to close the press, locate theplaten in predetermined relation with the type, move the toggles tooperative relation and actuate the toggles to apply printing pressure,thus providing a simple yet effective onehand operating means forprinting.

The present invention because of its unique shape and relation of partsas shown in the drawings has particular utility in that it can readilyoperate as a portable printing press. In this connection, the base,frame and operating components are compactly arranged and are made oflightweight material such as aluminum, magnesium or other materialcapable of withstanding printing pressures, and the operating handle forthe press can provide the means for carrying the portable press. This isaccomplished by providing the base with a locking clip 67 adapted toextend over the handle in its closed position of FIG. 3 to securely lockit to the base and lock the frame in its closed position of FIG. 3.Since the toggle links are in an actuated position when the handle is solocated, the elements of the press will be rigidly held in place so thatthey cannot be damaged or displaced during the'transportation andmovement of the press. If desired flanges 32 can be provided withextensions 32a to project into and close the openings 12a of the flanges12 when the frame is in closed position to prevent foreign material fromentering the press while it is being transported.

From the foregoing it will be seen that the present invention provides anovel press construction which is easy to operate, is of simpleconstruction, provides for pre-locating the paper to be printed justprior to the printing operation and for applying the printing pressure,all in a single one-direction operation of the hand-operated means, andprovides means whereby the operating handle can also function as acarrying handle for the press in the event it is desired to use thepress as a portable press.
